{{Useful Function}}
__NOTOC__
This function allow the value of a variable or expression to control the flow of program execution via a multiway branch.

''Note: This function is basically on the wiki to enable using it in other useful functions.''

==Syntax==
<syntaxhighlight lang="lua">var switch( arg )</syntaxhighlight>

===Required Arguments===
* '''arg''': The expression to compare.

===Returns===
Returns false if failed.

==Code==
<section name="Server- and/or clientside Script" class="both" show="true">
<syntaxhighlight lang="lua">
function switch(arg)
if(type(arg)~="table")then return switch end
local switching, default, done; --Default is nil

end
if(not done)then print("No action.") end
end

==Example==
<section name="Server" class="server" show="true">
This example compares a variable value and print out the result.
<syntaxhighlight lang="lua">
Player = 0 -- The variable to compare
switch -- Using the function
{ -- Using curly braces as it's a table
Player; -- Put the expression to compare in here and don't forget to end it with a semi-colon
0, function() print("It's 0") end, -- [ compare the value, do the function ] The first argument compares the value and the second execute the command inside the function if that compare is true.
